The Peugeot 9HK (DV6ETEDM) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features a 16‑valve DOHC layout, common rail direct injection, and a variable geometry turbocharger (VGT), delivering 88 kW (120 PS) and 300 Nm of torque. This compact unit was designed for efficiency and responsive low‑end performance in Peugeot's global small car and SUV lineup.
Fitted to models such as the 208, 308, and 3008, the 9HK was engineered for urban agil…
Production years 2015–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/PSA/9HK).
The Peugeot 9HK (DV6ETEDM) is a 1,560 cc inline‑four turbo‑diesel engineered for compact cars and SUVs (2015-2021). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑end torque and high fuel efficiency. Designed to meet Euro 6 standards, it balances urban drivability with low emissions.

The Peugeot 9HK (DV6ETEDM) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 3008-and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
The 9HK's primary reliability risk is EGR cooler failure, with elevated incidence in vehicles subjected to frequent short trips or high thermal loads. PSA internal data indicated a notable failure rate before 100,000 km in affected batches, while owner reports frequently cite coolant loss and overheating. Thermal cycling and infrequent highway driving increase cooler stress, making driving habits and prompt replacement critical.
Analysis derived from PSA technical bulletins (2015-2021) and owner-reported failure data (2018-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 9HK offers excellent fuel economy and strong low-end torque but has a known issue with the EGR cooler. With meticulous maintenance, using the correct 5W-30 oil, adhering to service schedules, and ensuring regular highway driving for DPF regeneration, it can be reliable. Later examples or those with the updated cooler are generally more robust.
The most frequent issues are EGR cooler failure, AdBlue system faults, turbocharger actuator problems, and DPF blockages. These are well-documented in PSA service bulletins and owner forums, often linked to driving habits, maintenance, or component wear.
This 1.6 BlueHDi 120 engine was used in the Peugeot 208 (2015-2021), 308 (2015-2021), and 3008 (2016-2021). It was a core engine for Peugeot's transition to Euro 6 compliance in its compact and SUV segments.
Yes, ECU remapping is possible and can yield safe power gains of +15-25 kW. The engine's internals are robust. However, increased power puts more strain on the turbo, clutch, and emissions systems (DPF/SCR), so enhanced maintenance and potential hardware upgrades are recommended.
Excellent. In a Peugeot 308, expect combined fuel economy of approximately 4.0 L/100km (71 mpg UK). Highway driving can return ~3.5 L/100km (81 mpg UK), while city driving may consume ~5.0 L/100km (56 mpg UK). Real-world figures vary with driving style and DPF health.
Yes. The 9HK is an interference engine. If the timing chain jumps or fails catastrophically, the pistons can collide with the open valves, causing severe internal damage. While the chain is designed for life, regular inspections for tensioner wear are advised.
Peugeot mandates oil meeting the PSA B71 2312 specification, typically a 5W-30 synthetic. Using the correct low-ash oil is vital for protecting the turbocharger, DPF, and SCR systems. Never use a lower specification oil.
